PRODUCTION DATA.
A 2.1 system generally refers to a system in which there are two full range speakers with a separate amplifier path for the speakers which reproduce the low-frequency content. In this system, two channels are presented to the amplifier via the digital input signal, these are driven into two single-ended speakers and are mixed into a third channel, conditioned to stream low-frequency content into a differentially connected speaker.
The 2.1 application is shown in Figure 72.
